BENDING ANGLE-IRONS,

SPEIFICATION forming part of Letters Patent No. 268,010, dated November 28, 1882.

Application filed May 23, was. (No modem To all whom it may concern:

Be itknown that I, GEORGE J. H. GOEHLER, a citizen of the United States, residing at Oincinnati, in the county of Hamiltonand State of Ohio, have invented certain new and. useful Improvements in Bending Angle-Irons, of which the following is a specification.

My invention consists in making an angular cove or notch in one of the webs of an angleiron and terminating the inner end of one side of said notch with a shoulder, that serves as an abutment or hearing, around which the other or uncut web is bent so as to produce a secure rounded corner, and without being compelled to heat or .weld the bar, as hereinafter more fully described, and pointed out in the claim.

In the annexed drawings, Figure 1 is a perspective view of an angle-iron the vertical web of which is to be bent at the dotted line Z Z. Fig. 2 is a similar view, but showing the tical web A at the line Z Z (seen inFig. 1,)

and without being compelled either to heat or weld the iron, I proceed as follows: The first operation consists in cutting, punching, or otherwise removing suflieient metal from the horizontal web B to form a. cove or notch, G,

the oppositesides or edges of which, cc, are so converged as to insure a close miter-joint when the bar is subsequently bent. The edge 0 runs directly into the web A, while the otheryedge, c, which is much more obtuse than the edge c, terminates at its inner end with a slightlycurved shoulder, D, which latter is carried in to the web A, as more clearly seen in Fig. 3. After this openingO c c D has been made the cold bar is bent with suitable appliances until the edges 0 c of the cove are brought in contact with each other, and thus form a perfect miter-joint, as seen at E imFigsA and 5. The result of this bending operation is to produce a rounded and symmetrical corner, a, on the uncut web A, which corner is perfectly solid and as secure as any other portion of the bar, the intrados of said corner abutting against the shoulder D, as more clearly shown in Fig. 5.

From this description it is evident said shoulder serves as a fulcrum or bearing around which the web A is gradually bent, thereby preventing any straining or injuring .of the fibers of the metal.

I claim as my invention- An angle-iron having one of its webs, B, coved or notched angularly at O c c, the edge 0 of said notch being carried into the uncut web A, while the opposite edge, 0, is joined to said web A by a shoulder, D, as and for the purpose described.

In testimony of which invention I hereunto set my hand.
